    Helpful support team

    Bought this after miscounting subdomains on a previous order. This one simply covers them all. New subdomains are covered automatically now, which is the real win. The only thing I would change is nothing. It did what it said.

    Does the job

    We had six subdomains each with their own certificate and renewal dates. Not any more. Installed the same certificate on three servers with no extra licence cost. Have moved the rest of our certificates over to them since.

    Not bad

    Bought this specifically so I could stop tracking separate expiry dates. The chain files came with it, so there was nothing to hunt down. Would have been five stars if the validation step had been explained upfront.

    Issued in minutes

    One certificate now covers every subdomain we run, which has saved a lot of admin. One CSR, one install, and every host name we own is covered. Would buy here again without hesitating.
